Say you run 2 miles in 20 minutes and your average heart rate was 175 bpm.
After 8 weeks of following a conditioning program you run 2 miles in 20:00 but your average heart rate is 160 bpm.
That's SIGNIFICANT progress. Your heart has become much more efficient to the task.
Heart Rate Zone training is a way to quantify conditioning training to modulate intensity.
For most go-getters, it makes sure you aren't pushing too hard too often.
It's also a way to know when to push harder as you adapt.
You have to keep challenging yourself to get stronger, faster, with more stamina.

Most of the longevity health benefits are realized by spending more time in Zones 2 & 3.
Your heart will become more efficient, circulation will improve, capillary beds will increase in density, fat oxidation will improve.
"150 minutes of moderate-to-vigorous aerobic physical activity per week had a 31% lower risk of dying from any cause, 29% lower risk of dying from cardiovascular disease, and a 15% lower risk of dying from cancer." PMID: 36854652

As you begin to work harder into Zones 4 & 5, lactic acid begins to build up and PRESS PAUSE on some of these positive adaptations.
Dr. Inigo recommends adding this type of training to the END of your aerobic sessions if you need to combine them to save time.
For example, on your 40 minute jog in Zones 2 & 3, where you can still nasal breathe and talk, at the very end in the final 2 minutes, GO ALL OUT, then be done for the day.

Finally - Zone Training has its limitations because it's impossible to know your exact max heart rate without testing. And testing can be dangerous if you aren't fit.
Age, gender, fitness levels, medications, and stress levels can all affect your max heart rate.
So like calories, know it's a guide and not a hard-and-fast rule.
